Why doesn't it rev past 4500rpm?


Bad Cat, bad coils, Bad fuel pump modulator or bad fuel pump (weak). These are places to start checking. My money is on a weak fuel pump.

Have you replaced the fuel filter . A clogged fuel filter can cause fuel filter can cause poor power problems . Try to accelerate quickly and see it the engine cuts out as it is running out of gas . If it does change the filter . Hope this corrects the problem
